Description

特許法第３０条第２項適用 本願発明の特許を受ける権利を有する者（出願人）である「クロバー株式会社」は、平成２９年１０月２日に、Ｃｌｏｖｅｒ Ｎｅｅｄｌｅｃｒａｆｔ，Ｉｎｃ．（クロバー株式会社の米国子会社）のウェブサイト（ｈｔｔｐ：／／ｗｗｗ．ｃｌｏｖｅｒ－ｕｓａ．ｃｏｍ／ｅｎ／，ｈｔｔｐ：／／ｗｗｗ．ｃｌｏｖｅｒ－ｕｓａ．ｃｏｍ／ｅｎ／ｈｏｍｅ／６８４－ｒｅｃｔｒａｃｔａｂｌｅ－ｓｅａｍ－ｒｉｐｐｅｒ－．ｈｔｍｌ）に証明書の添付書類に示す記事を掲載した。Application of Article 30, Paragraph 2 of the Patent Act On October 2, 2017, "Clover Co., Ltd.", the person (applicant) who has the right to obtain a patent for the invention of the present application, was notified by Clover Needlecraft, Inc. (US subsidiary of Clover Co., Ltd.) website (http://www.clover-usa.com/en/, http: //www.clover-usa.com/en/home/684-rectable-seam-ripper) -.Html) posted the article shown in the attached documents of the certificate.

本発明は、たとえば裁縫により形成された糸の縫い目をほどくために使用する糸切り具に関する。 The present invention relates to a thread trimmer used, for example, to unseam a thread formed by sewing.

裁縫時に糸の縫い目をほどくための道具として、いわゆるリッパーと呼ばれる糸切り具が知られている（たとえば特許文献１を参照）。当該糸切り具（リッパー）は、一般に、刃金具が柄に取り付けられた態様とされており、刃金具の先端に設けられた刃部を用いて縫い目をほどく。刃部は、切断刃を挟んで二股状に設けられた針部および球状部を有する。針部は、縫い目一つずつに差し込んで当該縫い目の糸を切るのに用いられる。球状部は、縫い目に沿って一気に糸を切るのに用いられ、球状部を布上で滑らせながら連続する縫い目に切断刃を差し込んでいく。特許文献１に開示された糸切り具においては、不使用時に刃金具に被せておくためのキャップが付属されている。 A so-called ripper, a thread trimmer, is known as a tool for unsealing threads during sewing (see, for example, Patent Document 1). The thread trimmer (ripper) is generally in a mode in which a blade fitting is attached to a handle, and a seam is unwound by using a blade portion provided at the tip of the blade fitting. The blade portion has a needle portion and a spherical portion provided in a bifurcated shape with the cutting blade interposed therebetween. The needle portion is inserted into each seam and used to cut the thread of the seam. The spherical portion is used to cut the thread at once along the seam, and the cutting blade is inserted into the continuous seam while sliding the spherical portion on the cloth. The thread trimmer disclosed in Patent Document 1 is provided with a cap for covering the blade fitting when not in use.

また、この種の糸切り具については、不使用時に刃金具を柄に収納可能とされたものも知られている（たとえば特許文献２を参照）。特許文献２に開示された糸切り具において、刃金具は、ねじ機構を用いてスライド移動するように、柄に保持されている。当該糸切り具の使用時には、柄の操作部を回転させることで、内蔵されたねじ機構により刃金具の先端刃部を柄の外部に進出させる。糸切り具の不使用時には、先端刃部を含む刃金具全体を柄の内部に収納させる。このような構成によれば、刃金具に被せるためのキャップ（別部材）を準備する必要がなく、キャップの紛失などの不都合を回避することができる。 Further, it is known that this type of thread trimmer can store the blade metal fitting in the handle when not in use (see, for example, Patent Document 2). In the thread trimmer disclosed in Patent Document 2, the blade fitting is held by the handle so as to slide and move using a screw mechanism. When the thread trimmer is used, by rotating the operation part of the handle, the tip blade part of the blade fitting is advanced to the outside of the handle by the built-in screw mechanism. When the thread trimmer is not used, the entire blade fitting including the tip blade is stored inside the handle. According to such a configuration, it is not necessary to prepare a cap (separate member) for covering the blade fitting, and inconvenience such as loss of the cap can be avoided.

しかしながら、特許文献２に開示された糸切り具は、刃金具をスライドさせるためのねじ機構を具備するので全体構造が複雑になる傾向にあり、使い勝手の点においても改善の余地があった。 However, since the thread trimmer disclosed in Patent Document 2 is provided with a screw mechanism for sliding the blade fitting, the overall structure tends to be complicated, and there is room for improvement in terms of usability.

図１、図２に示すように、刃金具２は、軸部２１および刃部２２を有する。軸部２１は、所定の軸線方向に延びており、横断断形状が略楕円状である。刃部２２は、軸部２１の先端に設けられている。刃部２２は、切断刃２２１、針部２２２、および球状部２２３を有する。切断刃２２１は、軸部２１の先端につながっており、当該軸部２１の先端側に刃先が向いている。針部２２２および球状部２２３は、切断刃２２１を間に挟んで二股状に設けられている。刃金具２は、たとえば鍛造により成形される。球状部２２３は、たとえば金属先端部が樹脂部で覆われた構成である。 As shown in FIGS. 1 and 2, the blade fitting 2 has a shaft portion 21 and a blade portion 22. The shaft portion 21 extends in a predetermined axial direction, and has a substantially elliptical cross-sectional shape. The blade portion 22 is provided at the tip of the shaft portion 21. The blade portion 22 has a cutting blade 221, a needle portion 222, and a spherical portion 223. The cutting blade 221 is connected to the tip of the shaft portion 21, and the cutting edge faces the tip side of the shaft portion 21. The needle portion 222 and the spherical portion 223 are provided in a bifurcated shape with the cutting blade 221 sandwiched between them. The blade fitting 2 is formed by, for example, forging. The spherical portion 223 has a structure in which, for example, a metal tip portion is covered with a resin portion.

柄１は、本体部１１、第１先端収納部１２、および第２先端収納部１３を有する。本体部１１は、柄１の大半を占めており、収納位置にある軸部２１を収納する。 The handle 1 has a main body portion 11, a first tip storage portion 12, and a second tip storage portion 13. The main body portion 11 occupies most of the handle 1, and stores the shaft portion 21 in the storage position.

第１先端収納部１２および第２先端収納部１３は、本体部１１の先端につながっている。図８に示すように、第１先端収納部１２は、針部２２２を収納する。図２、図４に示すように、第１先端収納部１２は第１ガイド面１２１を有しており、第１ガイド面１２１には針部２２２が通過可能な第１開口１２２が形成されている。図８に示すように、第２先端収納部１３は、球状部２２３の少なくとも一部を収納する。図２、図４に示すように、第２先端収納部１３は第２ガイド面１３１を有しており、第２ガイド面１３１には球状部２２３が通過可能な第２開口１３２が形成されている。図７、図８に示すように、刃金具２が収納位置をとるとき、針部２２２はその全体が柄１の内部に収納される。また、刃金具２が収納位置をとるとき、切断刃２２１の少なくとも一部が柄１の外部に露出する。 The first tip storage portion 12 and the second tip storage portion 13 are connected to the tip of the main body portion 11. As shown in FIG. 8, the first tip storage portion 12 stores the needle portion 222. As shown in FIGS. 2 and 4, the first tip accommodating portion 12 has a first guide surface 121, and the first guide surface 121 is formed with a first opening 122 through which the needle portion 222 can pass. There is. As shown in FIG. 8, the second tip storage portion 13 stores at least a part of the spherical portion 223. As shown in FIGS. 2 and 4, the second tip accommodating portion 13 has a second guide surface 131, and the second guide surface 131 is formed with a second opening 132 through which the spherical portion 223 can pass. There is. As shown in FIGS. 7 and 8, when the blade fitting 2 takes the storage position, the entire needle portion 222 is housed inside the handle 1. Further, when the blade fitting 2 takes the storage position, at least a part of the cutting blade 221 is exposed to the outside of the handle 1.

図５、図６、図９に示すように、本体部１１には、第１ガイド部１１１および第２ガイド部１１２が設けられている。本実施形態において、第１ガイド部１１１は、スライドベース３を移動させるための一対の対向する凹溝であり、直線状の方向ｘ（第１方向）に延びている。また、第２ガイド部１１２は、操作部材４を移動させるための一対の対向する帯状凸部である。第２ガイド部１１２は、第１ガイド部１１１に対して、方向ｘに直角である方向ｙ（第２方向）に離間し、かつ外側に凸状となるように湾曲または屈曲する。本実施形態では、第２ガイド部１１２が緩やかに湾曲するとともに屈曲する態様を表す。 As shown in FIGS. 5, 6 and 9, the main body 11 is provided with a first guide portion 111 and a second guide portion 112. In the present embodiment, the first guide portion 111 is a pair of facing concave grooves for moving the slide base 3, and extends in a linear direction x (first direction). Further, the second guide portion 112 is a pair of opposed strip-shaped convex portions for moving the operating member 4. The second guide portion 112 is separated from the first guide portion 111 in the direction y (second direction) perpendicular to the direction x, and is curved or bent so as to be convex outward. In the present embodiment, the second guide portion 112 gently bends and bends.

柄１は、たとえば所定の強度を有する合成樹脂からなる。柄１は、たとえば方向ｚ（方向ｘおよび方向ｙのいずれにも直角である方向）において２つ割れの分割片を、超音波溶着あるいは接着などの手法により一体的に接合したものである。 The handle 1 is made of, for example, a synthetic resin having a predetermined strength. The handle 1 is formed by integrally joining two split pieces in a direction z (a direction perpendicular to both the direction x and the direction y) by a technique such as ultrasonic welding or adhesion.

図５、図６、図８、図９に示すように、スライドベース３は、軸部保持孔３１、スライド嵌合部３２、係合凸部３３、および収納用凸部３４を有する。 As shown in FIGS. 5, 6, 8 and 9, the slide base 3 has a shaft portion holding hole 31, a slide fitting portion 32, an engaging convex portion 33, and a storage convex portion 34.

軸部保持孔３１には、刃金具２における軸部２１の基端部が圧入させられている。これにより、スライドベース３は、軸部２１の基端部を保持している。スライド嵌合部３２は、本体部１１（柄１）の第１ガイド部１１１に嵌入しており、第１ガイド部１１１に沿って移動可能である。これにより、スライドベース３は、第１ガイド部１１１（方向ｘ）に沿ってスライド移動可能である。 The base end portion of the shaft portion 21 of the blade fitting 2 is press-fitted into the shaft portion holding hole 31. As a result, the slide base 3 holds the base end portion of the shaft portion 21. The slide fitting portion 32 is fitted into the first guide portion 111 of the main body portion 11 (handle 1) and can move along the first guide portion 111. As a result, the slide base 3 can slide and move along the first guide portion 111 (direction x).

係合凸部３３は、スライド嵌合部３２よりも操作部材４が位置する方向ｙ一方側に突出している。係合凸部３３は、後述する操作部材４の係合凹部４３に係合する部分である。 The engaging convex portion 33 projects from the slide fitting portion 32 in the direction y on which the operating member 4 is located. The engaging convex portion 33 is a portion that engages with the engaging concave portion 43 of the operating member 4, which will be described later.

収納用凸部３４は、刃金具２（軸部２１）が収納位置にあるときに、本体部１１（柄１）に設けられた収納用孔１１３に嵌入する部分である。収納用凸部３４の外径寸法は、収納用孔１１３の内径寸法と同程度あるいは当該内径寸法よりも僅かに大きくされている。これにより、刃金具２が収納位置にあるときに、刃金具２をスライド動作させる際に相対的に大きい動作抵抗が生じる。上記の収納用凸部３４および収納用孔１１３は、本発明で言う第１抵抗付与機構を担う。 The storage convex portion 34 is a portion that fits into the storage hole 113 provided in the main body portion 11 (handle 1) when the blade fitting 2 (shaft portion 21) is in the storage position. The outer diameter dimension of the storage convex portion 34 is about the same as the inner diameter dimension of the storage hole 113 or slightly larger than the inner diameter dimension. As a result, when the blade fitting 2 is in the storage position, a relatively large operating resistance is generated when the blade fitting 2 is slid. The storage convex portion 34 and the storage hole 113 bear the first resistance imparting mechanism referred to in the present invention.

なお、刃金具２における軸部２１の先端側の部位は、軸部支持体５を介して本体部１１（柄１）に支持されている。軸部支持体５には、貫通孔５１が形成されており、この貫通孔５１に軸部２１が挿通されている。軸部２１の横断面サイズは、貫通孔５１の横断面サイズと同程度である。また、上記のように、軸部２１の基端部は、スライドベース３によって保持されている。これにより、軸部２１（刃金具２）は、方向ｘに沿ってスライド移動可能である。 The portion of the blade fitting 2 on the tip end side of the shaft portion 21 is supported by the main body portion 11 (handle 1) via the shaft portion support body 5. A through hole 51 is formed in the shaft portion support 5, and the shaft portion 21 is inserted through the through hole 51. The cross-sectional size of the shaft portion 21 is about the same as the cross-sectional size of the through hole 51. Further, as described above, the base end portion of the shaft portion 21 is held by the slide base 3. As a result, the shaft portion 21 (blade fitting 2) can slide and move along the direction x.

操作部材４は、摘み部４１、スライド嵌合部４２、および係合凹部４３を有する。摘み部４１は、使用者が刃金具２についてスライド移動させる際に指で押さえて力を与える部分である。摘み部４１は、柄１の外部に位置する。摘み部４１は、糸切り具Ａを正面から見て（方向ｚに見て）山形形状をなしており、また山形の傾斜部は細かい凹凸が連続している。これにより、摘み部４１は、指で押さえる際に適度なグリップ力が確保される。なお、摘み部４１は、本体部１１（柄１）に形成されたスリット１１４を通じて柄１の外部において延びる。 The operating member 4 has a grip portion 41, a slide fitting portion 42, and an engaging recess 43. The knob portion 41 is a portion that is pressed by a finger when the user slides and moves the blade fitting 2 to give a force. The knob 41 is located outside the handle 1. The knob portion 41 has a chevron shape when the thread trimmer A is viewed from the front (viewed in the direction z), and the inclined portion of the chevron has continuous fine irregularities. As a result, the grip portion 41 secures an appropriate grip force when pressed with a finger. The knob portion 41 extends outside the handle 1 through a slit 114 formed in the main body portion 11 (handle 1).

スライド嵌合部４２は、摘み部４１よりもスライドベース３が位置する方向ｙ他方側につながっている。スライド嵌合部４２は、本体部１１（柄１）の第２ガイド部１１２が嵌入しており、第２ガイド部１１２に沿って移動可能である。これにより、操作部材４は、第２ガイド部１１２に沿ってスライド移動可能である。 The slide fitting portion 42 is connected to the other side of the knob portion 41 in the direction y in which the slide base 3 is located. The slide fitting portion 42 has a second guide portion 112 of the main body portion 11 (handle 1) fitted therein, and can move along the second guide portion 112. As a result, the operating member 4 can slide and move along the second guide portion 112.

係合凹部４３は、スライドベース３が位置する方向ｙ他方側に臨む。この係合凹部４３には、スライドベース３の係合凸部３３が係合している。これにより、操作部材４（摘み部４１）を第２ガイド部１１２に沿って移動させると、スライドベース３およびこのスライドベース３に保持された軸部２１（刃金具２）は、方向ｘに沿ってスライド移動する。 The engaging recess 43 faces the other side in the direction y in which the slide base 3 is located. The engaging convex portion 33 of the slide base 3 is engaged with the engaging concave portion 43. As a result, when the operating member 4 (pinching portion 41) is moved along the second guide portion 112, the slide base 3 and the shaft portion 21 (blade metal fitting 2) held by the slide base 3 are moved along the direction x. Slide to move.

上記のように本体部１１（柄１）の第１ガイド部１１１は直線状の方向ｘに延びており、スライドベース３は、第１ガイド部１１１（方向ｘ）に沿ってスライド移動可能である。一方、第２ガイド部１１２は、外側に凸状となるように湾曲または屈曲する。本実施形態では、第１ガイド部１１１に対して、方向ｘに直角である方向ｙに離間し、かつ外側に凸状となるように緩やかに湾曲するとともに屈曲する。これにより、第２ガイド部１１２は、第１ガイド部１１１と平行ではない。 As described above, the first guide portion 111 of the main body portion 11 (handle 1) extends in the linear direction x, and the slide base 3 can slide and move along the first guide portion 111 (direction x). .. On the other hand, the second guide portion 112 is curved or bent so as to be convex outward. In the present embodiment, the first guide portion 111 is gently curved and bent so as to be separated from the first guide portion 111 in the direction y perpendicular to the direction x and to be convex outward. As a result, the second guide portion 112 is not parallel to the first guide portion 111.

そして、操作部材４の係合凹部４３にスライドベース３の係合凸部３３が係合しており、操作部材４を第２ガイド部１１２に沿って移動させると、スライドベース３は第１ガイド部１１１に沿って移動する。ここで、第１ガイド部１１１と第２ガイド部１１２とは平行ではないので、スライドベース３の第１ガイド部１１１に沿ったスライド動作の位置に応じて、係合凸部３３および係合凹部４３の係合深さが変化し得る。なお、上記の係合凸部３３および係合凹部４３は、本発明で言う連係機構を担う。 Then, the engaging convex portion 33 of the slide base 3 is engaged with the engaging concave portion 43 of the operating member 4, and when the operating member 4 is moved along the second guide portion 112, the slide base 3 becomes the first guide. It moves along the portion 111. Here, since the first guide portion 111 and the second guide portion 112 are not parallel to each other, the engaging convex portion 33 and the engaging concave portion depend on the position of the slide operation along the first guide portion 111 of the slide base 3. The engagement depth of 43 can vary. The engaging convex portion 33 and the engaging concave portion 43 are responsible for the linking mechanism referred to in the present invention.

また、本実施形態においては、操作部材４を第２ガイド部１１２に沿って移動させることで、刃金具２については、図８に示した収納位置と図５に示した進出位置との間でスライド移動可能である。図５、図８から理解されるように、刃金具２が収納位置にあるとき、係合凸部３３および係合凹部４３の係合深さが相対的に小さい。その一方、刃金具２が進出位置にあるとき、係合凸部３３および係合凹部４３の係合深さが相対的に大きい。そして、本実施形態においては、刃金具２が進出位置にあるとき、係合凸部３３の先端が係合凹部４３の底部に押圧接触している。これにより、刃金具２が進出位置にあるときに、刃金具２をスライド動作させる際に相対的に大きい動作抵抗が生じる。このように係合凸部３３が係合凹部４３に押圧圧接させられる構成は、本発明で言う第２抵抗付与機構を担う。 Further, in the present embodiment, by moving the operation member 4 along the second guide portion 112, the blade fitting 2 is moved between the storage position shown in FIG. 8 and the advance position shown in FIG. The slide can be moved. As can be seen from FIGS. 5 and 8, when the blade fitting 2 is in the retracted position, the engaging depth of the engaging convex portion 33 and the engaging concave portion 43 is relatively small. On the other hand, when the blade fitting 2 is in the advanced position, the engaging depth of the engaging convex portion 33 and the engaging concave portion 43 is relatively large. Then, in the present embodiment, when the blade fitting 2 is in the advanced position, the tip of the engaging convex portion 33 is in press contact with the bottom of the engaging concave portion 43. As a result, when the blade fitting 2 is in the advanced position, a relatively large operating resistance is generated when the blade fitting 2 is slid. The configuration in which the engaging convex portion 33 is pressed and pressed against the engaging concave portion 43 as described above bears the second resistance applying mechanism referred to in the present invention.

次に、上記構成の糸切り具Ａの使用方法および作用について説明する。 Next, the method and operation of the thread trimmer A having the above configuration will be described.

本実施形態の糸切り具Ａは、たとえば裁縫により形成された糸の縫い目をほどくのに利用される。糸の縫い目をほどく際には、まず、刃金具２について、図７、図８に示した収納位置から、操作部材４をスライドさせて図１、図２、図５に示した進出位置をとらせる。このとき、刃金具２の先端に設けられた刃部２２は全て柄１の外部に露出しており、この刃部２２を用いて糸の縫い目をほどく。刃部２２は、切断刃２２１を挟んで二股状に設けられた針部２２２および球状部２２３を有する。針部２２２を縫い目一つずつに差し込んで押し出すことで、切断刃２２１により当該縫い目の糸を切ることできる。球状部２２３は、縫い目に沿って一気に糸を切るのに用いられ、球状部２２３を布上で滑らせながら連続する縫い目に切断刃２２１を差し込む。 The thread trimmer A of the present embodiment is used, for example, to untie a thread formed by sewing. When unwinding the seam of the thread, first, for the blade fitting 2, slide the operation member 4 from the storage position shown in FIGS. 7 and 8 to obtain the advance position shown in FIGS. 1, 2, and 5. Let me. At this time, all the blade portions 22 provided at the tip of the blade fitting 2 are exposed to the outside of the handle 1, and the seams of the threads are unwound using the blade portions 22. The blade portion 22 has a needle portion 222 and a spherical portion 223 provided in a bifurcated shape with the cutting blade 221 interposed therebetween. By inserting the needle portion 222 into each seam and pushing it out, the thread of the seam can be cut by the cutting blade 221. The spherical portion 223 is used to cut the thread at once along the seam, and the cutting blade 221 is inserted into the continuous seam while sliding the spherical portion 223 on the cloth.

本実施形態の糸切り具Ａにおいて、刃金具２が図７、図８に示した収納位置をとるとき、針部２２２はその全体が柄１の内部に収納され、かつ切断刃２２１の少なくとも一部が柄１の外部に露出している。このような構成によれば、刃金具２が収納位置をとる場合においても、切断刃２２１の露出部分を用いて糸切りとして利用することができる。ここで、針部２２２は柄１の内部に収納されているので、針部２２２が指に突き刺さるなどの不都合を回避することできる。 In the thread trimmer A of the present embodiment, when the blade fitting 2 takes the storage position shown in FIGS. 7 and 8, the entire needle portion 222 is housed inside the handle 1 and at least one of the cutting blades 221. The portion is exposed to the outside of the handle 1. According to such a configuration, even when the blade fitting 2 takes a storage position, the exposed portion of the cutting blade 221 can be used as a thread trimmer. Here, since the needle portion 222 is housed inside the handle 1, it is possible to avoid inconveniences such as the needle portion 222 sticking into a finger.

柄１は、本体部１１と、各々が本体部１１の先端につながる第１先端収納部１２および第２先端収納部１３を有する。図５に示すように、本体部１１は、収納位置にある軸部２１を収納する。第１先端収納部１２は、針部２２２が通過可能な第１開口１２２を有する第１ガイド面１２１を有し、針部２２２を収納する。また、第２先端収納部１３は、球状部２２３が通過可能な第２開口１３２を有する第２ガイド面１３１を有し、球状部２２３の少なくとも一部を収納する。そして、第１ガイド面１２１および第２ガイド面１３１は、本体部１１側に向かうにつれて互いに近づく。このような構成によれば、刃金具２が収納位置をとるとき、針部２２２と球状部２２３の少なくとも一部とを、柄１の内部に適切に収納することができる。また、糸切りとして利用する場合、第１ガイド面１２１および第２ガイド面１３１の間に糸を通し進めることで、当該糸は第１ガイド面１２１および第２ガイド面１３１によって露出する切断刃２２１まで適切にガイドされる。 The handle 1 has a main body portion 11 and a first tip storage portion 12 and a second tip storage portion 13, each of which is connected to the tip of the main body portion 11. As shown in FIG. 5, the main body portion 11 stores the shaft portion 21 in the storage position. The first tip storage portion 12 has a first guide surface 121 having a first opening 122 through which the needle portion 222 can pass, and stores the needle portion 222. Further, the second tip storage portion 13 has a second guide surface 131 having a second opening 132 through which the spherical portion 223 can pass, and stores at least a part of the spherical portion 223. Then, the first guide surface 121 and the second guide surface 131 approach each other toward the main body 11 side. According to such a configuration, when the blade fitting 2 takes the storage position, at least a part of the needle portion 222 and the spherical portion 223 can be appropriately stored inside the handle 1. When used as a thread trimmer, the thread is passed between the first guide surface 121 and the second guide surface 131, so that the thread is exposed by the first guide surface 121 and the second guide surface 131. Will be properly guided.

糸切り具Ａは、第１ガイド部１１１に沿って移動可能なスライドベース３と、第２ガイド部１１２に沿って移動可能な操作部材４とを備える。スライドベース３は軸部２１の基端部を保持しており、操作部材４は、柄１の外部に位置する摘み部４１を有する。そして、スライドベース３および操作部材４は連係されている。このような構成によれば、柄１の外部に露出する摘み部４１をスライド移動させるといった簡単な操作によって、柄１に支持された刃金具２をスライド移動させることができる。したがって、刃金具２をスライド移動させるときの操作性に優れる。 The thread trimmer A includes a slide base 3 that can be moved along the first guide portion 111, and an operating member 4 that can be moved along the second guide portion 112. The slide base 3 holds the base end portion of the shaft portion 21, and the operating member 4 has a grip portion 41 located outside the handle 1. The slide base 3 and the operating member 4 are linked to each other. According to such a configuration, the blade fitting 2 supported by the handle 1 can be slid and moved by a simple operation such as sliding the knob portion 41 exposed to the outside of the handle 1. Therefore, the operability when the blade fitting 2 is slid and moved is excellent.

本実施形態の糸切り具Ａにおいては、刃金具２が図７、図８に示した収納位置にあるときに、刃金具２をスライド動作させる際に相対的に大きい動作抵抗が生じる。また、刃金具２が図２、図５等に示した進出位置にあるときにも、刃金具２をスライド動作させる際に相対的に大きい動作抵抗が生じる。このような構成によれば、刃金具２が進出位置にあるときと収納位置にあるときのいずれの使用状態においても、刃金具２が意図せずにスライド移動することを防止することができる。 In the thread trimmer A of the present embodiment, when the blade fitting 2 is in the storage position shown in FIGS. 7 and 8, a relatively large operating resistance is generated when the blade fitting 2 is slid. Further, even when the blade fitting 2 is in the advanced position shown in FIGS. 2, 5 and the like, a relatively large operating resistance is generated when the blade fitting 2 is slid. According to such a configuration, it is possible to prevent the blade fitting 2 from unintentionally sliding and moving regardless of whether the blade fitting 2 is in the advanced position or the storage position.

以上、本発明の実施形態を説明したが、本発明の技術的範囲は上記した実施形態に限定されるものではない。本発明に係る糸切り具の各部の具体的な構成は、発明の思想から逸脱しない範囲内で種々な変更が可能である。 Although the embodiments of the present invention have been described above, the technical scope of the present invention is not limited to the above-described embodiments. The specific configuration of each part of the thread trimmer according to the present invention can be variously changed without departing from the idea of the present invention.
